Complete the table below:
For each of the following sets pick the compound with the highest conductivity in a 1 M aqueous solution.
(Enter the number at the top of the column containing the correct answer.)
1 2 3 Answers
a HCl HC2H3O2 H2PO4–
b KNO3 Ca(NO3)2 HNO3
c CH3OH NaOH HOC6H5
d Li2CO3 Na2CO3 K2CO3
e NaCl MgCl2 AlCl3

Look for the compound which in a dilute solution has the most ions. for instance, in b

KNO3 is completed ionized,2 ions per molecule
Ca(NO3)2, three ions, but one of them carries two charges, so in fact one moleucle can break up to carry 5 net charges.
HNO3, 100 precent dissoacated, but two ions per molecule.
